September 21, 2010 — Space shuttle Discovery arrived early Tuesday at Launch Pad 39A at NASA's Kennedy Space Center to be readied for its final mission to space. STS-133 is scheduled to lift off on Nov. 1 with a crew of six, delivering a new storage module for the International Space Station (ISS). The flight will mark Discovery's 39th launch and the second-to-last for NASA's nearly 30-year space shuttle program.

Hours after Discovery was secured atop Pad 39A, collectSPACE joined a small group of media for a rare opportunity to photograph the spacecraft from above and below during a tour of the launch complex. Later on Tuesday, the pad's rotating service structure (RSS) will be moved to surround Discovery, hiding the orbiter from view but also protecting it and providing access to load its payload as it is prepared to launch to space one last time.
